Abstract
An optical fiber fusion-splicer that fusion-splices at least a pair of optical fibers that includes: a pair of electrode rod units each having a pointed end portion that faces each other and a pair of mounting bases that each support the electrode rod units. Abutting portions of the optical fibers are interposed between the pair of electrode rod units. Each of the electrode rod units includes: an electrode rod that fusion-splices the optical fibers by discharge heating and a main heat dissipation member that protrudes from an outer circumferential surface of the electrode rod. Each of the pair of mounting bases supports a position of the electrode rod units that is closer to a base end side than a pointed end portion of the electrode rod.
